The letters C designate stay 01 steadying ehains, of which there is oneon each 0f t-he outer sides 0f the handle H. Eaeh 0f th'e ehains at itsfront end connects at 0 with the end 0f thehandle, and,as extendedrearwardly, they each pass down over one of the pulleys pfand down underone 0f the pnlleys P t0 rise is arranged on and eonnected t0 the shaft Sand b a belt passing over ehe top and sides of seid wheel With the lowerends of said hell; connected t0 a pin p*, arranged in the ears A uponthe brake-shaft S This brakeshaft journals in bearings b, attaehed t0 aplate N that is offset from and eonn ected t0 the boom B at n The letterd' designates a lever keyed t0 the brake-shaft S, and R a rod pivotallyeonnected by a pin a t0 the lever d and therefrom extended rearwardly t0COI1T1GC'D With the lever d*, that is pivoted at p and provided withoperating-handles 71 h by which eonnecnion With said belt 011 thebrake-shaft wheel B the said belt 1nay be caused to tighten upon saidWheel, so as t0 control the movement 0f the steadying-ehains upon thepulleysl, and thus regulate and control the sliding 0f the dipper-handleH in the slideways w As thus made and arranged, when' Ehe heitehain O isallowedto unwind from the drum and the dipper by gravity descends int0the water t0 reach the bottom the dipper-hahdle H slides in the ways 10the slide W turning on the shaf S to adapt itself so the position 0f thedipperhandle while the chains C as the handle descends, 1nn over thepinions 19 p and under the pulley P on ehe shaft ehains npon the handle,that in a measure, by means of pulleys on the slide, control themovement 0f the dipper-handle to their combination with the brake-wheel,the funetion of the latter being merely aecessory. Furlzhermore, I donot 1innit my invention o0 the particular f01xn 0f brake-wheel shown, asany other well-known means that Will perform the same oifice insnbstantially the sarne manne1 may be 'used.

Having thus deseribed 1ny invention, what I elaim, and desire t0 secnreby Letters Patent, is

.1.- The combination, With the boonn B, made with the slide W, pivotedthereto and having the pulley P and pinions 19 19 at each side,substantially as deseribed, 0f the dipper-handle H, having thesteadying-chains O ab each side thereof, eaeh arranged t0 run on one ofsaid pulleys P and 0 n two pinions p? 13 substantially in the manner asand for the purposes sei: forth.

2. The cornbination, with the bo o1n B, 0f the slide W, made wioh theslide-passage 10 and having the pinions 19 19 a1; eaeh side thereof, theshaft S t0 pivot said slide t0 said boom, the pulley P a'rranged uponsaid shai't a each side 0f said slide-passage, the dipperhandle H, 1nadeto straddle said boornand arranged in said slide-passage w andsteadying-ehains C one arranged upon each side of said handle, each ofsaid ehains being at its ends connected to said handle and arranged t0intermediately l'un upon one 0f oho pulleys and 011 two 0f said pinionsab eaeh side of the handle, substantially in the manner as and f01 thepurposes sei: f'0rth.

3. The combination, with the boorn B, 0f the slide WV, made With theslide-passage 10 and pivoted to said boom by the shaft S the pnlley Pand pinions 10 10 arranged at each Iob side 0f said slide-passage way,the brake-' wheel B arranged on said shaft S said brake- Wheel beingprovided With a brake-belt, and the dipper-handle H, 1nade to straddlesaid boom and arranged within said slide-passage, said dipper-handlebeing at each side pro- Vided With a steadying-chain that a1; its endsconnects with ohe handle and intermediately runs on one 0f seid pulleysand 0n two 01": the pinions ab eaeh side of the slid e, substantially inthe manner as and f0r the purpose3 set forth.
